Scientists reveal aging or depend on parents

Over the years, researchers at the University of Lund in Sweden have been working on the analysis of the body's aging process. Today, researchers are investigating the birth of small birds to see if the length of the telomeres they carry at birth affects the later stages of aging. process.

The genetic composition of our body cells includes many genes arranged on the chromosomes, and the part of the end of chromosomes is called telomere, which can protect the chromosome from damage and mutual adsorption; the longer the telomere is, the longer the chromosome maintenance function is, and vice versa. The shorter the telomere time, the shorter the chromosomes will function; therefore, more and more research has focused on chromosome telomeres in recent years to reveal their effects on the aging process in humans and other animals.

In this study, the researchers observed that the telomere lengths of new born individuals will change greatly. For this reason, they carried out relevant studies to explain the reasons for this phenomenon; Dr. Asghar Muhammad stated that during the early stages of individual life, There are significant differences in the length of chromosome telomeres between individuals such as humans and animals.

The researchers used a 30-year study of giant salamanders living in Kvismaren Lake in southern Sweden, and studied data for analysis to find out which genetic factors affect the length of their chromosome telomeres, based on a series of measurements. The researchers compared the telomere lengths of newborns and their parents when they were young. The results showed that the length of chromosome telomeres in giant salamanders depends on the hereditary and non-hereditary factors with fairly even distribution. The young calves were born. The older the female individual is, the longer the chromosome telomeres are. The female individual, for example, can affect the level of antibodies or hormones in the egg yolk. These factors may then affect the telomere length after 10 days and make it rapidly. Shorter.

The researchers said that the effects of chromosomal telomeres in humans and giant salamanders may behave differently. Previous studies have shown that the non-hereditary factors that affect the telomeres of human offspring are more obvious than fathers, but not the mother; Muhammad said that in the human population, there may be a correlation between the age of the father and the chromosome length of the child's body. The older the father, the longer the chromosome telomeres of the offspring.
